Ranked: The Megaregions Driving the Global Economy

If you’ve ever flown cross-country in a window seat, chances are, the bright lights at night have caught your eye. From above, the world tells its own story—as concentrated pockets of bright light keep the world’s economy thriving.

Today’s visualization relies on data compiled by CityLab researchers to identify the world’s largest megaregions. The team defines megaregions as:

• Areas of continuous light, based on the latest night satellite imagery
• Capturing metro areas or networks of metro areas, with a combined population of 5 million or higher
• Generating economic output (GDP) of over $300 billion, on a PPP basis

The satellite imagery comes from the NOAA, while the base data for economic output is calculated from Oxford Economics via Brookings’ Global Metro Monitor 2018.

It’s worth pointing out that each megaregion may not be connected by specific trade relationships. Rather, satellite data highlights the proximity between these rough but useful regional estimates contributing to the global economy—and supercities are at the heart of it.

From Megalopolis to Megaregion

Throughout history, academics have described vast, interlinked urban regions as a ‘megalopolis’, or ‘megapolis’. Economic geographer Jean Gottman popularized the Greek term, referring to the booming and unprecedented urbanization in Bos-Wash—the northeast stretch from Boston and New York down to Washington, D.C.:

This region has indeed a “personality” of its own […] Every city in this region spreads out far and wide around its original nucleus.

—Gottmann, Megalopolis (1961)

By looking at adjacent metropolitan areas rather than country-level data, it can help provide an entirely new perspective on the global distribution of economic activity.

Where in the world are the most powerful urban economic clusters today?

The Largest Megaregions Today

The world’s economy is a sum of its parts. Each megaregion contributes significantly to the global growth engine, but arguably, certain areas pull more weight than others.

Altogether, these powerhouses bring in over $28 trillion in economic output.

Unsurprisingly, Bos-Wash reigns supreme even today, with $3.6 trillion in economic output, over 13% of the total. The corridor hosts some of the highest-paying sectors: information technology, finance, and professional services.

The largest city in Brazil, São Paulo, is the only city in the Southern Hemisphere to make the list. The city was once heavily reliant on manufacturing and trade, but the $780 billion city economy is now embracing its role as a nascent financial hub.

On the other side of the world, the cluster of Asian megaregions combines for $8.7 trillion in total economic output. Of these, Greater Tokyo in Japan is the largest, while Shandong might be a name that fewer people are familiar with. Sandwiched between Beijing and Shanghai, the coastal province houses multiple high-tech industrial and export processing zones.

The data is even more interesting when broken down into economic output per capita—Abu-Dubai churns out an impressive $86,200 per person. Meanwhile, Delhi-Lahore is lowest on the per-capita list, at $14,946 per person across nearly 28 million people.

Where To Next?

This trend shows no sign of slowing down, as megacities are on the rise in the coming decade. Eventually, more Indian and African megaregions will make its way onto this list, led by cities like Lagos and Chennai.

For the past decade, manufacturers and governments all over the world have been preparing for the adoption of self-driving cars—with the promise of transformative economic development.

As autonomous vehicles become more of a looming certainty, what will be the wider impacts of this monumental transition?

Which Countries are Ready?

Today’s interactive visual from Aquinov Mathappan ranks countries on their preparedness to adopt self-driving cars, while also exploring the range of challenges they will face in achieving complete automation.

The Five Levels of Automation

The graphic above uses the Autonomous Vehicles Readiness Index, which details the five levels of automation. Level 0 vehicles place the responsibility for all menial tasks with the driver, including steering, braking, and acceleration. In contrast, level 5 vehicles demand nothing of the driver and can operate entirely without their presence.

Today, most cars sit between levels 1 and 3, typically with few or limited automated functions. There are some exceptions to the rule, such as certain Tesla models and Google’s Waymo. Both feature a full range of self-driving capabilities—enabling the car to steer, accelerate and brake on behalf of the driver.

The Journey to Personal Driving Freedom

There are three main challenges that come with achieving a fully-automated level 5 status:

1. Data Storage
   Effectively storing data and translating it into actionable insights is difficult when 4TB of raw data is generated every day—the equivalent of the data generated by 3,000 internet users in 24 hours.
2. Data Transportation
   Autonomous vehicles need to communicate with each other and transport data with the use of consistently high-speed internet, highlighting the need for large-scale adoption of 5G.
3. Verifying Deep Neural Networks
   The safety of these vehicles will be dictated by their ability to distinguish between a vehicle and a person, but they currently rely on algorithms which are not yet fully understood.

Which Countries are Leading the Charge?

The 20 countries were selected for the report based on economic size, and their automation progress was ranked using four key metrics: technology and innovation, infrastructure, policy and legislation, and consumer acceptance.

The United States leads the way on technology and innovation, with 163 company headquarters, and more than 50% of cities currently preparing their streets for self-driving vehicles. The Netherlands and Singapore rank in the top three for infrastructure, legislation, and consumer acceptance. Singapore is currently testing a fleet of autonomous buses created by Volvo, which will join the existing public transit fleet in 2022.

India, Mexico, and Russia lag behind on all fronts—despite enthusiasm for self-driving cars, these countries require legislative changes and improvements in the existing quality of roads. Mexico also lacks industrial activity and clear regulations around autonomous vehicles, but close proximity to the U.S. has already garnered interest from companies like Intel for manufacturing autonomous vehicles south of the border.

How Autonomous Vehicles Impact the Economy

Once successfully adopted, autonomous vehicles will save the U.S. economy $1.3 trillion per year, which will come from a variety of sources including:

• $563 billion: Reduction in accidents
• $422 billion: Productivity gains
• $158 billion: Decline in fuel costs
• $138 billion: Fuel savings from congestion avoidance
• $11 billion: Improved traffic flow and reduction of energy use

With the adoption of autonomous vehicles projected to reduce private car ownership in the U.S. to 43% by 2030, it’s disrupting many other industries in the process.

• Insurance
  Transportation will be safer, potentially reducing the number of accidents over time. Insurance companies are already rolling out usage-based insurance policies (UBIs), which charge customers based on how many miles they drive and how safe their driving habits are.
• Travel
  Long distance traveling in autonomous vehicles provides a painless alternative to train and air travel. The vehicles are designed for comfort, making it possible to sleep overnight easily—which could also impact the hotel industry significantly.
• Real Estate
  An increase in effortless travel could lead to increased urban sprawl, as people prioritize the convenience of proximity to city centers less and less.

Defining the parameters for this emerging industry will present significant and unpredictable challenges. Once the initial barriers are eliminated and the technology matures, the world could see a new renaissance of mobility, and the disruption of dozens of other industries as a result.
